Tresset [83]

Answer: 1 27

A certain forest covers an area of 1900km^2. Suppose that each year this area decreases by 7.75%. What will the area be after 14

yarga [219]

Answer:

Assume that 1900km^2 is 1900.

If that happens, The equation of that will look like...

1900 - (1900 x 7.75% x 14)%.

1900 x 7.75% are 147.25.

and 147.25 x 14 are 2061.5.

so... there will be no forest after 14 years.(harsh)

Hope it helps!
